Bug#924151: grub2-common: wrong grub.cfg for efi boot and fully encrypted disk

[Roger Shimizu]

After reading release announcement of D-I RC2 [1], it's got my
attention that there's an well written doc [2].
It's mentioned that /boot should be in LUKS1, due to grub doesn't
support LUKS2 yet [3], which is why this ticket originally reported, I
guess.

I confirmed with /boot set up in LUKS1, everything works fine.
It‘d configure non encrypted /boot when in D-I, then after finishing
D-I, and reboot to system, manually make LUKS1 for /boot partition.
Detail procedure is in the doc [2].
